Paper presented at the The 31st International Ocean and Polar Engineering Conference, June 20–25, 2021
Paper Number: ISOPE-I-21-3135
... Abstract In this study, we present a solution for water waves with shear current and non-vanishing vorticity over a flat bed. The solution satisfies all boundary conditions and governing equations including the Euler equation. It is shown that two types of vorticities are possible according...

Paper presented at the The 28th International Ocean and Polar Engineering Conference, June 10–15, 2018
Paper Number: ISOPE-I-18-554
... ABSTRACT A direct numerical method is proposed to simulate nonlinear water waves with nonzero constant vorticity in a two-dimensional channel of finite or infinite depth. Such a vortical distribution represents a background shear current that varies linearly in the vertical direction. Our...

Paper presented at the The Twenty-fifth International Ocean and Polar Engineering Conference, June 21–26, 2015
Paper Number: ISOPE-I-15-161
... Abstract We obtain a general solution for the initial value problems of water waves with a shear current of uniform vorticity beneath the surface in three dimensions. Linearized governing equations and boundary conditions including the effects of gravity, a distributed external pressure...

Paper presented at the The Twenty-second International Offshore and Polar Engineering Conference, June 17–22, 2012
Paper Number: ISOPE-I-12-488
... ABSTRACT: The interaction between a non-uniform shear current and two nonlinear propagating waves in deep water is investigated by means of an analytic method for highly nonlinear problems, namely the homotopy analysis method (HAM). The convergent series solutions are obtained in case...
